We are going to make a circuit that will make the
bulb light up.
To do this we need………
…batteries in a battery holder…
…a light bulb…
…electrical wires and crocodile clips.

The battery holder has a positive and a negative side. The batteries are not
the same way up.
Positive side
Negative side

When you have collected all of the equipment you can start to make the
circuit.

First you must connect one of the crocodile clips to one of
the battery sides
Then you need to connect the other
wire.
Now the bulb will light.

The circuit starts from the negative side of the battery holder.
The electric current runs through the light bulb…..
…and continues along the wire to the positive
side of the battery holder.
This completes the circuit.

The circuit only works when everything is
connected correctly.
Look at the next few pictures. See if you can guess whether the circuits will light up or not. Can you see what might be
wrong with them?

Will this circuit light?
This circuit will not light because the wires are not all connected.
When the wires are all connected the circuit will work.

Will this circuit light?
This circuit will light because
everything is connected properly.
This keeps the circuit working properly.

Will this circuit light?
This circuit will not light because the batteries are
facing the same way up in the battery
holder.When the batteries are the right way
round the circuit will work.

Will this circuit light?
This circuit will not light
because one of the
wires is attached to the glass
part of the light bulb. When the wire is properly
connected to the battery side the circuit will work.

Keeping everything correctly connected is the only way the circuit will work.
